equalizing lever.

shown which eonvey cooling air to the electric motors.l Instead of mounting the leaf springs 7 direetly on the journal boxes, I have shown them as being mounted thereon through springs 1S). rlhe links 8 support the side frames through hangers 20 and springs 21.

In order to support the equalizing lever ll by the levers 10', hangers 2Q are pivotally connected to the levers l() and are provided with knife edges 23 on which the equalizing lever 11 rests. The spring 12 is shown as being fastened beneath the truck frame to the member 17 by means of bolts 24C. If the center of gravity of the spring supported mass is low, the bolts 24 fastening the spring 12 to the truck frame may be omitted, in which ease the upward pull of the parts on the links 13 and the weight of the truck frame exerting a downward force will keep 'the spring 12 in Contact with the member 17, the stops 25 preventing the displacement of the spring. Such an arrangement allows a freer movement of the spring supported mass. Furthermore I desire it to be understood that I aim in the appended claims to cover such a modification as well as any others which do not depart from the spirit and scope of my invention.

1lWhat I claim as new and desire to secure by Letters Patent of the United States, is

l. In a locomotive truck, tivo wheel axles, journal boxes therefor, a truck frame hav.- ing side frames in which said journal boxes are slidably mounted, a spring arranged above each journal box and mounted thereon, links and a lever for hanging each of said side frames on the two springs on each side jointly, an equalizing lever supported by said .first mentioned levers and extending erosswise of said truck frame, and means for resiliently supporting said truck f aine on said equalizing lever.

9,. In a locomotive truck, wo Wheel axles,

l1. In# a` locomotive truck, two wheel axles, journal boxes therefor, a truck frame having sidel frames on which. said journal boxes are slidably mounted, a leaf spring arranged above each journal box with its middle point mounted thereon, links for connecting one end of said springs to said side frames, a lever on each side of said truck, links for connecting the other end of said spring on eachv side with each of said levers', an equalizin'g lever su ported by said lirst mentioned levers an 'extending crosswise of said truck, a leaf spring fastened crosswise of the said truck frame between said wheel axles, and links for sup porting said last mentioned leaf spring lfrom said equalizing lever.

In witness whereof, I have hereunto set my hand this 23rd day of July, 1914.
